Gentlemen,
I am confused at the comments of "narrow band" - and considering that 160m
is 200khz wide. These two ideas do not seem to go together.
So I wonder if there exists an assumption is that the RTTY contest MUST run
ONLY in the 1.800-1.810 segment - as is suggested by the ARRL band plan.
Perhaps there is some FCC regulation that prohibits RTTY operation across
the entire band? Or some other international agreement prohibiting
operation beyond this point?
Assuming that there exists no official (meaning legal) prohibition on
operation, then we should rethink this assumption. Why? SSTV and other
"wide band" transmissions are allowed all the way up to 2.0. RTTY is a far
more efficient use of bandwidth than SSTV by definition. And as such, it
seems to me that there exists no logical reason to restrict operation to
only a 10khz band segment.
In fact, I believe that a big RTTY contest run in a segment similar to that
occupied on other bands in big contests would provide minimal disruption to
the other activities running on the band as it is. For the typical RTTY
contest considering 20m (the meat-and-potatoes of contest bands), stations
are typically running from about 14.075 - 14.120 or so roughly. Smaller
contests, there is less of a spread with most action focused in the
.080-.100 range. Due to the nature of what it takes to get a signal out on
top band, I think even a big rtty contest would have most of it's action
confined to a 20-30khz band spread.
Unless I have made an incorrect assumption, it seems to me that the question
could be reshaped as:
1. Assuming a gentlemen's agreement existed which had an operation band of
approximately 1.860-1.890 and with 1.875 assumed to be center point where we
"start here and look up/down to find an open freq" philosophy,
2. then would you support RTTY contesting on 160m?
